The lung cancer mortality rate for women is expected to increase by over 40% by 2030, according to a new study. Conversely, the breast cancer mortality rate is expected to decrease.
Lung cancer is the type of cancer that kills the most. According to the World Health Organization (WHO), 1.69 million people died in 2015. In recent years, the number of deaths has decreased, but only in men as more women smoke today than in the past. According to a new study published by the American Association for Cancer Research, by 2030, the mortality rate of lung cancer among women will increase by 40%, while the breast cancer mortality rate will drop.
A rise almost everywhere in the world
Researchers at the University of Catalonia in Barcelona used the WHO Lung and Breast Cancer Mortality databases for women between 2008 and 2014 in 52 countries. According to their projections, the overall mortality rate of lung cancer among women is expected to increase by 43% between 2015 and 2030. For the same period, the breast cancer mortality rate is expected to decrease by 9%.
Variations by country
These projections vary by geographical area. In America and Asia, the lung cancer mortality rate will be lower compared to Europe and Oceania. For breast cancer, the mortality rate will most likely increase in Asia, although it will remain lower than in Europe. These differences are related to lifestyles: smoking has been developing in women for a long time in Europe and Oceania, resulting in an increase in the number of women affected by lung cancer. Asian populations are increasingly adopting the Western way of life, but the latter is associated with higher rates of obesity and higher alcohol consumption, which can increase the risk of breast cancer.
7 million Tobacco deaths
Tobacco is not only responsible for lung cancer, it also increases the risk of others diseases. According to a 2017 WHO publication, it causes 7 million deaths each year. If smoking does not decline around the world, in 2030, 8 million people could die from smoking each year.
